| molecularNote | A neomycin selection cassette replaced exon 5 coding sequences, corresponding to amino acids 162-246 required for protein-protein interactions with MyoD family members. Northern blot and RT-PCR analysis on RNA derived from E14.5 embryos demonstrated that no stable transcript was produced from this allele. |
